The needed mass of methane is approx. 3 g.
5.33g CH4 must be burned to emit 267 kJ of heat.
if you heat it
If you burn it, it will.
Yes, it does if the heat is high enough.
If they are heated they will absorb heat, like any substance does, up to the point where they are hot enough to react with oxygen and start burning, then they emit heat.
5.33g CH4 must be burned to emit 267 kJ of heat.
Yes. Hard woods burn slowly and emit a lot of heat, whereas soft woods burn quickly and do not emit as much heat.
Normally Plasma televisions do not emit smell. When a TV is brand new, a part might heat up and burn off a piece of glue. Otherwise, it should not emit a smell. Normally, it would not emit a smell.
Avocado wood (and any natural wood) will burn. Heat value is similar to elm. More heat value than pine, less than oak.
they emit heat when their is a recombination of electron and holes
Yes. The electric motor does emit some heat. Also, when the car is stopping, forward energy is converted into heat.
yes
Uranium don't emit directly heat; under nuclear fission the kinetic energy released and the energy of radiations is converted to heat and after to electricity.
An object that absorbs heat well will also emit heat well. The object will emit heat until equilibrium is reached with its surroundings.
They emit: gamma rays, radio waves, and x-rays. Some stars emit T.V. rays
To emit heat
light and heat
